Study of some heamatological parameters of infected pigeons Columba livia and coots Fulica atra infected with Hadjelia truncata nematods

Abstract

This study was conducted in Al-Najaf Al-Ashraf province, from the beginning of September/ 2019 until January 2020, to identify the effect of the nematode Hadjelia truncata, on some heamatological parameters of two types of birds, coot Fulica atra and pigeon Columba livia. Samples of worms, isolated from birds’ gizzards were sent to the Natural History Museum in Baghdad, as they are being studied for the first time, for the purpose of diagnosing samples, while traditional methods were adopted to detect heamatological parameters, for both infected and uninfected birds in order to make comparisons between them, where diagnostics revealed the Infection of Columba livia and Fulica atra with Hadjelia truncata. For both types, the results showed a clear decrease in hemoglobin (Hb), and the volume of packed blood cells (PCV) compared to the control groups, where the values ​​were (8.5 g/ml) and (25.6%) in Fulica atra, respectively, while they were in Columba livia (15.6 g/ml) and (36.6%), respectively. The increase was clear and noticeable for the WBC numbers of both Fulica atra and Columba livia, as they were (31.9 × 109/ L) and (1.0 × 109/ L) respectively. For the biochemical indicators, the results showed a decrease in the glucose concentration ratios for Fulica atra by (61mg/dl), and an increase for Columba livia by (162 mg/dl). The results of the affected birds of both types were in agreement, in the high blood cholesterol concentration, as the Fulica atra recorded (338 mg/dl), while the Columba livia recorded (233 mg/dl), and the proportions of Ca + 2 and the AST enzyme were also in agreement in terms of decrease for both the two birds were the values ​​(11.4 mg/dl) and (15 U/L) for the Fulica atra, respectively, and (8.5 mg/dl) and (19.2 U/L) for the Columba livia, respectively. The results differed in protein and bilirubin concentrations, which showed an increase in Fulica atra by (5.7 IU/L) and (0.8 mg/dl), respectively, and a decrease in Columba livia, which recorded (3.0 IU/L) and (0.5 mg/dl), respectively.
